Twenty beech populations distributed over the natural range of beech in the target area were analyzed using 12 isozyme loci. Analysis of genetic distances revealed the existence of geographical differentiation patterns. Allelic frequencies were estimated for a square network of 300 points covering the territory of the Czech Republic employing kriging as an optimum spatial interpolation method. Cluster analysis based on allelic profdes of the kriging points made it possible to divide the investigated area into eight seed zones. Inra Elsevier Paris.

La proposition de regions de provenances en République Tchèque pour le hêtre commun Fagus sylvatica L. a été basée sur 1 étude de son polymorphisme isoenzymatique. Pour cela vingt populations de hêưe réparties sur Taire d extension naturelle dans le territoire examine ont été analysées pour 12 loci isoenzymatiques. L analyse des distances génétiques a montré 1 existence d une structuration géographique. Les frequences alléliques ont été estimées par la methode de krigeage methode d interpolation spatiale pour un reseau quadratique de 300 points recouvrant 1 ensemble du ter-ritoire tchèque.
